Zinc ore has several different kinds, such as sphalerite, smithsonite, zincite willemite, troostite, hemimorphite etc.so far; minerals containing zinc have been more than 30 that have been discovered in Nature. Sphalerite is the ore that has the most widely distributed, followed by smithsonite. In calcite, smithsonite is such ore with high hardness and high proportion. Sphalerite is the majority ore that contains zinc in nature, smithsonite is much less relatively. Sphalerite is the most widespread of zinc mineral, mainly for hydrothermal genesis, almost always symbiosis with galena. it is easy weathering into smithsonite in surface. All these kinds of zinc ore have large economic values.
Peru is rich in mining resources, which is one of the 12 big mining countries in the world. There are mainly copper, lead, zinc, tin, silver, iron, and oil, etc. bismuth, vanadium reserves are the highest in the world respectively; copper reserve accounts for a third in the world; silver and zinc are ranked fourth in the world. Proven oil reserves are 400 million barrels and natural gas has 7.1 trillion cubic feet. Forest coverage rate is 58%, an area of 77.1 million hectares, which is the second only to Brazil in South America. Water and Marine resources is extremely abundant and so is fishery resource, fish meal production is ranked among the top of the world.in 2009, Mithril production is the world's highest, copper production is the world's second and so is zinc output; tin production is the third in the world and the gold production is the world's sixth.
As for zinc ore can be applied into many fields, refined zinc is necessary for many relative fields. Due to the rich zinc mineral resources, zinc ore mining plant in Peru is very popular as well. In zinc ore mining plant, some mining equipment is necessary, such as jaw crusher, cone crusher, impact crusher, grinding machines, beneficiation machines and so on. Allthis equipment is produced by shanghai SBM, a famous manufacturer and supplier of crushing and grinding machines in the world. All the products produced by shanghai SBM are high qualified and tested by relative authoritative department.
For all these machines have their own characteristics, such as jaw crusher is suitable for the more hard stones while cone crusher and impact crusher are more suitable for the less hard stones. When these machines are at work, there are some things needed to pay more attention.
For example, when Raymond mill is at work, there are several things needed to be noticed. For Raymond mill operating normally, clients should formulate "equipment maintenance security operating system" for the equipment in order to guarantee the Raymond mill long-term safe operation. At the same time the necessary maintenance tools and grease and the corresponding accessories are at demands. Raymond mill roller device using time is not more than 500 hours. After 500 hours, the roller should be replaced. The roller set inside of the rolling bearing must be cleaned and the damaged parts should be replaced in a timely manner. Refueling tools is available for manual pumps. In using process, Raymond mill should be responsible for the supervision by fixed worker. The operator must have a certain technical knowledge of this equipment. Operators must take the necessary technical training to understand the principle of Raymond mill performance, familiar with the operation procedures before installation of Raymond mill.
Also, there are some special things that should be paid more attention when these machines are at work. Clients can take advances from experts of these machines and make sure these machines can be used properly.
